In 1967 U.S. intelligence was surprised[8] to find that the Soviet Union was producing a large fighter aircraft, the MiG-25 'Foxbat'.[9] It was not known in the West at the time that the MiG-25 was designed as a high-speed interceptor, not an air superiority fighter,[10] so its primary asset was speed, not maneuverability. The MiG-25's huge tailplanes and vertical stabilizers (tail fins) hinted at a very maneuverable aircraft, which worried the Air Force that its performance might be better than its U.S. counterparts. In reality, the MiG's large fins and stabilators were necessary to prevent the aircraft from encountering inertia coupling in high-speed, high-altitude flight.[
